The videotape had not yet been posted on extremist web sites Tuesday, the sixth anniversary of the attacks. But the IntelCenter, a monitoring group in suburban Washington D.C., said it had obtained the videotape privately - and it released two still photos taken from the tape.

One showed bin Laden in front of a brown backdrop. The other showed one of the Sept. 11 hijackers, Walid al-Shehri, who was killed in the attack, in front of the picture of the Trade Center.

The IntelCenter also released a brief quote by bin Laden from the new tape in which he mentions the suicide hijacker,al-Shehri.

"This talk of mine consists of some reflections on the will of a young man who personally penetrated the most extreme degrees of danger and is a rarity among men: one of the 19 champions (may Allah have mercy on them all)," said bin Laden, according to the monitors.
